The headline is wrong. There is no "swift justice." It's just that the AG has been asked to "look into it." Hardly what I call "swift justice."
By the time Sessions gets done "looking into it," the mayor will have moved onwards and perhaps upwards in the Dem hierarchy. There is also a possibility that the leadership of this country will have turned toward the Democrats and nothing will come of it.
Of course, Republicans aren't really interested in stemming the flow of illegals into this country either.
